Chopin added cautionary naturals before b in bar 61 and d1 in bar 62 in GC (→GE1); they were added in EE3 too). The second one of them was omitted in GE2, yet returned in GE3. The natural before f1 at the end of bar 61 is an addition, introduced most probably at the time of proofreading of FE. None of these signs are present in EE1 (→EE2).
All sources repeated 
before g
3 at the beginning of the 4th group of semiquavers in bar 61, while in GC (→GE) and EE also before g in the L.H. EE added also a before the next g, most probably due to g3 in the R.H.
